Název v původním jazyce

On the occurrence of Spinidelphinulopsis whaleni (Gastropoda) in the Late Triassic (early Norian) Cornwallis Limestone, Kuiu Island, southeastern Alaska (Alexander terrane) and its paleobiogeographic significance

Popis výsledku v původním jazyce

The gastropod Spinidelphinulopsis whaleni Blodgett, Frýda and Stanley, 2001, was originally described from late Carnian or early Norian strata on the Oregon side of Hells Canyon in the Wallowa terrane (Oregon, Idaho, and Washington). It is probably alsopresent in early Norian strata at Green Butte, Wrangell Mountains (Wrangellia terrane) of southern Alaska. The common presence of this species and many other shared gastropod species has previously been cited as being evidence for close biogeographic linkage between the Wrangellia and Wallowa terranes. Quite dissimilar, coeval gastropod faunas are found in the in-board Alexander terrane of southeastern Alaska. Explanation for the now known widespread distribution of this neritimorph species in a numberof different terranes in eastern Panthalassa during Late Triassic times seems to be best attributed to it having a relatively long-lived planktotrophic larval stage, allowing it to be relatively well dispersed.
